Tire tread



FIG. 1 is a perspective view of a tire tread showing my new design, it being understood that the tread pattern is repeated throughout the circumference of the tire, the opposite side being substantially the same as that illustrated; and,

FIG. 2 is an enlarged fragmentary front elevation view of the tread pattern of FIG. 1 showing my new design.

The broken line disclosure of a tire sidewall and inner bead is for illustrative purposes only and forms no part of the claimed design. 

The ornamental design for a tire tread, as shown and described.
